SAVE THESE INSTRUCTIONS

KICKBACK SAFETY

Understanding Kickback

• Rotational Kickback can happen when the upper tip of the guide

bar contacts an object while the chain is moving. This can cause

the chain to dig into the object and momentarily stop moving.

The guide bar is then kicked up and back toward the operator in

a lightning-fast reverse reaction.

• Pinch Kickback can happen when the wood on either side of a cut

closes in and pinches the moving saw chain along the top of the

guide bar. This can cause the chain to instantly stop. The chain

force is then reversed, causing the saw to move in the opposite

direction, sending the saw straight back toward the operator.

• Pull-In can happen when the moving chain on the bottom of the

guide bar hits a foreign object inside the wood. This can cause

the chain to suddenly stop. The saw is then pulled forward and

away from the operator, which could potentially result in the loss

of control of the saw.

Kickback Safety Precautions

• Do not rely exclusively upon the safety devices built into the

unit.

• Do not extend arms above shoulder height.

• Do not make cuts with the tip of the guide bar.

• Do not let the tip of the guide bar contact any object, such as a

log, branch, ground or other obstruction.

• Do not operate the unit with one hand! Serious injury to the

operator, helpers or bystanders may result from one-handed

operation. This unit is intended for two-handed use. Always grip

the unit firmly with both hands when the unit is running.

• Stand slightly to the left of the unit to avoid being in the direct

line of the saw chain.

• Never start the saw when the guide bar is inside an existing cut.

Be extremely careful when re-entering a cut.

• Always begin a cut with the unit running at full speed. Fully

squeeze the throttle control and maintain a steady cutting

speed. Slower speeds increase the chance of kickback.

• Follow the manufacturer’s sharpening and maintenance

instructions for the saw chain.

• Only use replacement bars and chains specified by the

manufacturer or the equivalent. These are available from

authorized service dealers. Use of any unauthorized parts or

accessories could lead to serious injury to the operator or

damage to the unit and will void the warranty.

• Use devices, such as low-kickback chains and reduced-

kickback guide bars, which reduce the risks associated with

kickback. There are no other replacement components for

achieving kickback protection in accordance with CSA Z62.3.

• Low-kickback saw chain is chain that has met the kickback

performance requirements of ANSI B175.1-2000 and is in

accordance with CSA Z62.3. Do not use a replacement chain

unless it has met these requirements for the specific model. As

saw chains are sharpened, some of the low kickback qualities

are lost and extra caution should be used.

DANGER:Kickback may occur when the nose

or tip of the guide bar touches an object, or when the

wood closes in and pinches the saw chain in the cut. In

some cases, tip contact may cause a lightening-fast

reverse action, kicking the guide bar rapidly back to wards

the operator. Pinching the saw chain along the top of the

guide bar may push the guide bar rapidly back towards the

operator. Either of these reactions may cause a loss of

control over the saw, which could result in serious injury to

the user. Contact with foreign objects within the wood can

also induce a loss of chain saw control.

WARNING: To prevent serious injury, never perform

maintenance on the unit while it is running. Always turn the

unit off and allow it to cool. Prevent the unit from starting

accidentally: For gas-powered units, disconnect the spark

plug wire. For electric-powered units, disconnect the unit

from the power source. For battery-powered units, remove

the battery.

NOTE: Some maintenance procedures may require special tools or

skills. If you are unsure about these procedures, take the unit to

an authorized service dealer.

WARNING: To prevent serious personal injury, always

wear heavy gloves when handling the saw chain.

4. Make the third cut as close to the tree trunk as possible. Cut

upward, from the underside of the limb stub. Use the top of the

guide bar to make this cut. Cut a third of the way through the

diameter of the limb (Fig. 4).

5. Make the fourth cut directly above the third cut. Cut downward,

from the top of the limb stub. Use the bottom of the guide bar to

make this cut. Cut completely through the limb stub to meet the

third cut (Fig. 4). This will remove the limb stub.

SETTING THE CHAIN OIL ADJUSTMENT SCREW

Lubricating oil will automatically flow from the chain oil reservoir

onto the saw chain during operation. Use the chain oil adjustment

screw to adjust the flow of oil:

1. Insert a 3/32-inch Allen wrench into the chain oil adjustment

screw (Fig. 10).

2. Turn the chain oil adjustment screw counterclockwise to

increase the oil flow.

3. Turn the chain oil adjustment screw clockwise to reduce the oil

flow.

WARNING: If the chain oil reservoir becomes empty, the

chain oil adjustment screw hole becomes clogged, or the

saw chain fails to receive proper lubrication in any way, the

saw chain will overheat. This can cause irreparable damage

to the unit and serious personal injury.

ADJUSTING THE SAW CHAIN TENSION

Proper saw chain tension is extremely important. Check the saw

chain tension before and during operation. Maintaining proper saw

chain tension will improve cutting performance and prolong the life

of the saw chain.

NOTE: A new saw chain and guide bar will need readjustment after

as few as five (5) cuts. This is normal during the break-in period.

The interval between future adjustments will lengthen quickly.

1. Loosen the bar-retaining nuts so they are hand tight (Fig. 5).

2. Hold the guide bar tip up and use a flat-head screwdriver to turn

the chain-tensioning screw (Fig. 8). Turning the screw clockwise

will tighten the saw chain. Turning the screw counterclockwise

will loosen the saw chain. Depending upon the temperature of

the saw chain, it should be snug to the guide bar (Fig. 9).

3. While wearing heavy-duty work gloves, move the saw chain

back and forth on the guide bar to be sure the chain moves

freely and is in proper mesh with the sprocket. Never move the

chain with your bare hands.

NOTE: If the saw chain binds or does not rotate easily, turn the chain-

tensioning screw counterclockwise, slowly, to loosen the saw

chain. Move the saw chain back and forth until it moves freely.

4. Hold the guide bar tip up and securely tighten the bar-retaining nuts.

CAUTION: The guide bar, saw chain, and saw bearings

will wear more rapidly if the saw chain is not properly

tensioned.

MAINTAINING THE GUIDE BAR

1. Rotate the guide bar frequently, at regular intervals (for example,

after every 5 hours of operation), to ensure even wear on the top

and bottom of the guide bar.

2. Clean the guide bar groove and oil passages whenever the saw

chain is removed, when the unit has been used heavily or when

the saw chain appears dirty. Use a screwdriver, putty knife, wire

brush or similar instrument to remove debris from the guide bar

groove (Fig. 11). Use a soft wire that is small enough to insert

into the chain oil discharge hole to remove any debris from the

hole (Fig. 12).

3. Frequently check the guide bar for damage. Feathering and

burring of the guide bar rails (the ridges on either side of the bar

groove) is a normal process of guide bar wear. Such faults

should be smoothed with a file as soon as they occur. A guide

bar with the following faults should be replaced:

• Wear inside the guide bar rails that permits the chain to lay

sideways

• Bent guide bar

• Cracked or broken rails

• Spread rails

MAINTAINING THE SAW CHAIN

The saw chain will wear with use, causing the chain to stretch. This

is normal. When it is no longer possible to obtain a correct chain

tension adjustment, the saw chain will need to be repaired by an

authorized service dealer or replaced.

Always use a replacement saw chain designated as “low-kickback”

or a saw chain that meets the low-kickback performance

requirements. A standard saw chain (a chain that does not have the

kickback-reducing guard links) should only be used by an

experienced professional chain saw operator.

Fig. 11

Fig. 12

Chain Oil Discharge Hole

WARNING: Unless you have experience and specialized

training for dealing with kickback (refer to the Safety

section), always use a low-kickback saw chain, which

significantly reduces the danger of kickback. Low-kickback

saw chain does not completely eliminate kickback. A low-

kickback or “safety chain,” should never be regarded as

total protection against injury.

CLEANING AND STORAGE

CLEANING

Use a small brush to clean the outside of the unit. Do not use strong

detergents. Household cleaners that contain aromatic oils such as

pine and lemon, and solvents such as kerosene, can damage plastic.

Wipe off any moisture with a soft cloth.

Lightly coat the guide bar and saw chain with a corrosion-inhibiting oil.

WARNING: To avoid serious personal injury, always stop

the unit and allow it to cool before cleaning or maintaining

the unit.

STORAGE

• Loosen the saw chain if the chain tension was adjusted during

operation. The saw chain will contract as the unit cools, which

could damage the unit if the chain is too tight.

• Cover the guide bar and saw chain with the scabbard.

• Never store a fueled unit where fumes may reach an open flame

or spark.

• Allow the engine to cool before storing.

• Lock up the unit to prevent unauthorized use or damage.

• Store the unit in a dry, well-ventilated area.

• Store the unit out of the reach of children.

Long-term Storage

• Thoroughly clean the unit and inspect it for any loose or

damaged parts. Replace damaged parts and tighten loose

screws, nuts or bolts.
